In this article, we propose a depth map refinement method that increases the quality of immersive video. The proposal highly enhances inter-view consistency maps (estimated or acquired by any method), crucial for achieving required fidelity virtual view synthesis process. described method, only information from is used, as use texture can introduce errors in refinement, mostly due to color inco...

      There are various methods and models for land evaluation. These methods are classified according to the number of used resources. The best resources capabilities or potentials and land use can be found by analyzing one of the main resources, in the lands close relations to ecologic resources exist. Soil has a great potential for introducing the studied region specifications. Hence, it cha...

Since depth-image-based rendering (DIBR) is one of the rendering processes to generate virtual views from the texture image and the depth map, we investigate DIBR as a core technique for threedimensional television. In this paper, we propose a new scheme to generate multi-view images using DIBR. In order to improve visual quality of multiview images at newly exposed areas, we preprocess the dep...

Landslides are among the most damaging natural hazards in mountainous regions. In this study, landslide hazard zonation was conducted in the Baba Heydar Watershed using logistic statistical regression to determine landslide hazard areas. First, a landslide inventory map was prepared using aerial photograph interpretation and field surveys. Next, ten landslide conditioning factors including alti...

Undoubtedly, land degradation linked to desertification causes a decrease in qualitative and quantitative features of natural resources. This research aimed to assess land desertification by local residents and their role in controlling desertification in Isfahan province, Iran in 2016. The criteria were soil climate, vegetation, erosion, and demography. The indicators of soil texture, stone fr...

to investigate pedological criterion on land degradation in quaternary rock units, at first, a part of the shoor watershed area was selected. after distinguishing target area, slope classes, land use and geology maps were created, then map of units were founded by overlaying and crossing these maps. in this research three indices of erodibility, salinity and permeability of soils were considere...
